Answer:
Explanation:
The formula for centripetal acceleration is
. Filling in:
and
so
v = 6.1 m/s
So, Speed of light in Rock salt is 1/1.54 times speed of light in vacuum. Therefor Speed of light in Rock salt is less [1.94 x 10⁸m/s ] compared to speed of light in vacuum =C = 3 x 10⁸ m/s.
Answer:
B. Technician B only
Explanation:
Technician A says that valve overlap is the number of crankshaft degrees that both valves are closed. Technician B says that valve overlap is the number of degrees that both valves are open. Who is right? A. Technician A only B. Technician B only C. Both technicians A and B D. Neither technician A nor B
Valve overlap is when both the intake and exhaust valves are open. This occurs towards the end of the exhaust stroke, the intake valves are opened just before all the exhaust gases are released, providing more time for the intake air to enter the engine. Valve overlap must be shorter for a petrol/gasoline engine because the engine is drawing in fuel as well as air through the intake. ...it is not so for a sport car
the inlet valve and exhaust valve are located at the head of the engine. fuel enters the engine through the intake valve.
When an object is slowing down, the acceleration is in the opposite direction as the velocity.
Answer:
This all simply due to the size of the two water bodies question and the your body size in a bath tub the water is small enough to allow the upthrust displace water out if the tub whereas in a lake the water is bigger and your body size is smaller to allow any noticeable upthrust that would cause an overflow
